I'm not very talkative unless I'm talking to close friends, or in a political discussion.
I went to a party at my boss' place. He knows I'm normally not the most social person around, so he was pretty amused when I got into a 3+ hour long political debate with another guest. Only reason it ended that early was it got to be about 6:30 am and we were falling asleep. We didn't even have the chance to get into economics.
I had a girlfriend who always talked about stupid little petty crap so I could just say "ohhh..... uh huh.... yeah.... " periodically and that was enough to keep the conversation going. She'd call when I was asleep and I'd actually talk to her in my sleep. She never even noticed, and the only either of us would find out is when she'd bring up something we apparently discussed or agreed to do and I had no clue what she was talking about.
